Abstract
The utility model discloses a forming cutter for processing an internal spline. The forming cutter comprises a mounting base (1) and a forming cutter arbor (2), wherein the front part of the forming cutter arbor (2) is a forming cutter arbor part (21); the back part of the forming cutter arbor (2) is a locating bar part (22); the back end of the locating bar part (22) is connected with the mounting base (1); and the spline is formed in the forming cutter arbor part (21). The spline processed and formed by the forming cutter is high in precision and small in error; and the processing quality is further improved.
Description
Technical field:
The utility model relates to internal spline machine-shaping technical field, more specifically to a kind of molding cutter of internal spline processing usefulness.
Background technology:
Prior art generally all adopts hydraulic press extruding or punch forming in the processing internal spline, it is to utilize the spline molding cutter of high rigidity to mold spline at inner hole wall, and the spline molding cutter is to be driven by oil hydraulic cylinder, but because cutter need match with the endoporus of workpiece, therefore cutter is restricted dimensionally, the intensity that also is cutter for this reason is not too large, the phenomenon of strain can take place in process, therefore the spline precision that processes of such cutter is not high, error ratio bigger in addition can make that workpiece is whole and scrap.
The utility model content:
The purpose of this utility model just is to provide a kind of molding cutter of internal spline processing usefulness, and the spline precision height of its machine-shaping, error are little, have further improved the quality of processing.
For achieving the above object, the molding cutter of a kind of internal spline processing usefulness of the present utility model, it comprises mounting seat and moulding knife bar, the front portion of moulding knife bar is moulding knife bar portion, the rear portion of described moulding knife bar is backstay portion, the rear end of this backstay portion is connected with mounting seat, forms spline in the described moulding knife bar portion.
Preferred as technique scheme, moulding knife bar portion is made by the alloy material of high rigidity.
Preferred as technique scheme, moulding knife bar portion and backstay portion are formed in one and form.
Preferred as technique scheme, the junction of moulding knife bar portion and backstay portion is conus portion.
Preferred as technique scheme, backstay portion and mounting seat are by one-body molded or welding manner is fixed together.
Preferred as technique scheme offers some installing holes that install and fix usefulness on the mounting seat.
The beneficial effects of the utility model are: the utlity model has backstay portion, in processing, carry out the location of concentricity by backstay portion, make cutter in the process of processing, can not be offset owing to factors such as strain take place, the spline that it processes has higher precision, error is in the extreme little, has further improved the precision of processing work.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is perspective view of the present utility model
Fig. 2 is operation principle schematic diagram of the present utility model
Among the figure: 1, mounting seat; 2, moulding knife bar; 3, frame plate; 4, workpiece; 5, counterdie; 6, patrix; 11, installing hole; 21, moulding knife bar portion; 22, backstay portion; 211, spline; 221, conus portion
The specific embodiment:
Therefore the following stated only for embodying the preferred embodiment of the utility model principle, does not limit protection domain of the present utility model
Be illustrated in figure 1 as the embodiment of the molding cutter of a kind of internal spline processing of the utility model usefulness, it comprises mounting seat 1 and moulding knife bar 2, the front portion of moulding knife bar 2 is moulding knife bar portion 21, the rear portion of described moulding knife bar 2 is backstay portion 22, the rear end of this backstay portion 22 is connected with mounting seat 1, forms spline 211 in the described moulding knife bar portion 21.
In the present embodiment, moulding knife bar portion 21 is made by the alloy material of high rigidity, and in order to allow the precision that improves cutter, moulding knife bar portion 21 is formed in one with backstay portion 22 and forms.
In addition, moulding knife bar portion 21 is conus portion 221 with the junction of backstay portion 22, the mode that this conus portion 221 can lead to chamfering realizes, and conus portion 221 in fact plays the effect of a transition, make and can not bump when backstay portion 22 stretches into, make that it can be more steady in the process of action, backstay portion 22 and mounting seat 1 can be by one-body molded or welding manner is fixed together, specific to considering for firmness in the present embodiment, backstay portion 22 is fixed together by one-body molded with mounting seat 1, offer four installing holes 11 that install and fix usefulness on the mounting seat 1 symmetrically, this four installing holes 11 have been arranged, and mounting seat 1 can be fixed it by bolt.
Under working condition as shown in Figure 2, mounting seat 1 is by being bolted on the frame plate 3, workpiece 4 then is to close tight being clamped in this matched moulds afterwards by patrix 6 and counterdie 5, and this matched moulds moves downward in the oil hydraulic cylinder drive, 21 in moulding knife bar portion passes the endoporus that counterdie 5 stretches into workpiece 4 and processes in this process, backstay portion 22 then matches with the centre bore of counterdie 5, it can play guiding function, make moulding knife bar portion 21 not be offset when stretching into the endoporus of workpiece 4, it can also play a restriction simultaneously, make moulding knife bar portion 21 in the process of processing, also can keep a concentricity preferably, the precision of the spline of can deducting a percentage to a great extent processing with the endoporus of workpiece 4.
